Edit host file by Batch File

Update Host file with bath script

Today I got a mail from one of my senior is there a way by which we can add multiple address in host file with out consuming lot of time and my simple reply was we need to use batch file for that. They said ok do it but actually I have never done it before so I had no other option than Google.

I searched for Google but every time I got a lengthy result and comment on those results were not positive it worked for some people and for some people it doesn't. I was wondering If I can have a simplest way for this as my previous backup script.

So I decided if I can print few lines in host file and it worked.Now no need of writing a long batch script for editing host file.

Here is the command

echo test.test.com>>c:\Windows\System32\drivers\etc\hosts

You can add as many line as you want to add and save the file as hostentry.bat

Let me explaint you meaning of each word here

Echo it will print the words written after it Its the ip of the server

Test.test.com Its the dns name of the server

>> it save the printed data in given file

c:\Windows\System32\drivers\etc\hosts Host file location for printg the data

Needless to say that IP and domain name would get change as per your server detail

if your oprating system is not in c driver please chagne the drive latter as per needed.

Just run the batch file and you are done for updating your host entry.

Hope it was usefull for you.

Please let me know if you face any problem in it.

Almost exactly what I'm looking for...
However, How can you check first if it already exists? And if not, write the line, if it does, quit.

if test.test.com in c:\Windows\System32\drivers\etc\hosts Exitst

then do nothing

echo test.test.com>>c:\Windows\System32\drivers\etc\hosts

Any suggestions?

Andrés said...

worldofrugs i think you can do that using c++
reading / writing on the host file.

my Q? here is, is there a way to ERASE a line?

Unknown said...

if the batch runs multiple times it keeps adding in the same lines. is there a way for it to not run again after it runs once?

We were also looking for an easy command-line way to edit the hosts file, not only adding entries but also deleting them.

Since echo will never give you that, I wrote a small command line tool that does exactly that: add and remove entries from the hosts file. It also does not allow duplicates.

you can find it on github: teamaton toolbelt,
just click on the download button and choose the HostsEditor.exe.

You can also fiddle with the source code, it's all accessible.

Have fun,

Amazing just what I have been looking for just make sure you run as Administrator

Hi all,

we also needed to edit the hosts file programmatically and adding lines using echo was just not enough.

After reading several comments where people ask how to avoid duplicates and erase lines, I wrote a small tool that does all of that: the teamaton HostsEditor.
You can read more details on our dev blog: a simple hosts file editor.
It is an .exe that you can call from the command line and you can verify the source code on GitHub.

I hope someone out there will find this useful.

Oliver said...

Just one more thing: for some it might not be obvious but on our GitHub toolbelt page you need to click on the Download button or use the following link to directly download the HostsEditor.exe.

Very useful!

echo. >>c:\Windows\System32\drivers\etc\hosts
echo demo>>c:\Windows\System32\drivers\etc\hosts

With "echo." we put a line break and avoid having two hosts on the same line (invalidating the first).
